Can Dogs Eat Marshmallows?

I have heard many ways and reasons that people feed marshmallows to their dogs. Some say it’s a great way to hide a pill, others like it for a training treat, and some just can’t say no to their dog if they are enjoying a marshmallow themselves. 

Technically, yes dogs “can” eat marshmallows. Just like they “can” eat diapers, crayons, whole balls of yarn, stuffed toys, and a host of other items they can consume and hope it passes through alright. The real question is, should you feed your dog marshmallows or should you panic when your dog gets hold of a marshmallow?

Are There Any Benefits of Giving Marshmallows To My Dog?

Most marshmallows contain gelatin which can be good for dogs. Gelatin is mostly protein which is vital to all canines. Moreover, the protein in gelatin is very ealisy broken down for use by your dog. The positives of marshmallows stop there. 

What are the Dangers of Marshmallows for Dogs?

We all know that marshmallows are sweet and delicious and that is why we humans love them. They typically contain corn syrup, sugar, corn starch, artificial colors and flavors, and some times xylitol. Xylitol in even small amounts can be toxic to dogs, more on that in a minute. What if the marshmallows don’t contain xylitol? Marshmallows still contain sugar and sugar is carbs. Dogs have no need for carbs at all in their diet. All they need is protein and fat. So, why feed them carbs?

Not only are carbs completely unnecessary to the canine diet they can be quite dangerous and damaging. A small number of carbs once in a while may be alright. But high carbs, on a daily basis in a dog’s diet can make him more likely to develop cancer, obesity, leaky gut, fungal and yeast infections, pancreatitis, and diabetes. 

Cancer cells, bad bacteria in the gut, fungi and yeast love carbs as a food source. In fact, they all thrive on carbs. Is one marshmallow going to do this? Probably not. But if you add one marshmallow to your dog’s diet and he already eats a high-carb diet, that marshmallow definitely won’t help.

Marshmallows and other cards raise blood sugar levels quickly. This causes the body to release insulin. Insulin is the only hormone dogs, and people, have to lower blood sugar. They have 8 hormones that can raise blood sugar. Seems like dogs are more prepared to raise their blood sugar if there is a lack of carbs then they are prepared to deal with huge amounts fo carbs. 

Insulin’s main purpose is to move the sugar out of the bloodstream and into cells. Often the sugar is stored in the cells as fat. 

When dogs eat a high carb diet or lots of marshmallows, over time, it can cause the dog’s cells to become insulin resistant. Insulin resistance can lead to weight loss resistance and diabetes, among other problems you don’t want your precious pet to have. 

Carbs, like the sugar found in marshmallows, are the only food that significantly raises blood sugar and cause a large release of insulin. Protein may have a tiny effect, and fat usually has none at all. Which makes protein and fat superior energy sources for dogs.


Xylitol, Sweets and Their Danger to Dogs

Now for xylitol. Xylitol is a naturally occurring substance and can be found in tiny amounts in several plants including lettuces, berries, corn, hardwoods, and other plant life. It is used as a sugar substitute because it has much fewer carbs than sugar. 

When a dog eats xylitol it triggers the dog to release insulin, however, the body does not need to do this. So, the insulin that is released lowers the blood sugar to unsafe levels, this is called hypoglycemia. This can take 10-60 minutes after the xylitol is eaten. Hypoglycemia is a potentially life-threatening situation. Xylitol can also cause liver failure and seizures.

How Much Xylitol Can Your Dog Eat?

50 mg for every pound of dog. This small amount is enough to do damage. The higher the amount consumed the higher the risk of liver failure and death. 

Xylitol can be found in many foods these days. It is especially popular as a sweetener in sugar-free gums, candies, and sometimes baked goods. To be honest you should keep your dog safe from such foods anyway, whether they have xylitol or not they are not good for your dog. 

If your dog ingests a product containing xylitol, immediately call your vet or the Pet Poison Helpline.

Symptoms of xylitol poising can develop within 15-30 minutes and include: vomiting, weakness, lack of coordination, lethargy, tremors, seizures, and coma. 

Read labels of the foods you consume, especially sugar-free foods, so you know if they could be toxic to your pet. If they contain toxic ingredients to your pet, keep them in a place your dog cannot get to them.

Are Marshmallows Bad for All Dogs?

Yes, marshmallows are bad for dogs and ideally they should not eat them at all.

If they happen to get hold of one marshmallow every now and then it might be okay, as long as the marshmallow doesn’t contain any harmful ingredients like xylitol.

Here is a list of breeds that are more prone to diabetes, and should never be given sweet treats like marshmallows: Alaskan Malamute, Beagle, Boxer, Cairn Terrier, Chow Chow, Dachshund, Doberman Pinscher, Finnish Spitz, German Shepherd Dog, Golden Retriever, Hungarian Puli, Keeshond, Labrador Retriever, Miniature Pinscher, Miniature Schnauzer, Old English Sheepdog, Poodle, Samoyed, Schipperke, Springer Spaniel, Tibetan Terrier, and the West Highland White Terrier.

Are There Marshmallows That Are Safe for Dogs?

There is a “marshmallow” product made for dogs, but it is still not safe. It is still full of carbs including honey and oats. Regular feeding of these types of treat will spike insulin levels and lead down a slippery slope to insulin resistance, obesity, and possibly worse. 

So, what is a good treat for your dog?

I recommend a single-ingredient, meat treat. These treats are full of protein with perhaps a little fat and no carbs. Plus, these treats are going to be a higher value for most dogs, which is great for training!
